I needed to replace an 8 port serial card. Installed a new Digi Neo card in an XW4600 controller with the latest Neo driver for it and now the Keysight software does not work. After rebooting the controller and test head, when starting DGN, the DGN window appears; however, the window is empty and grayed out. If you start the GUI and press 'load', the screen will show "Connecting to testhead", and hangs.
Any ideas what causes this?
